Intelligence for the property decisions that matter.
Which rules of thumb have quietly stopped being true, whether what happened to your unit is normal, and which decisions actually change the outcome. We test explanations rather than assert them, and publish what fails alongside what holds. How we measure.

Research notes
Findings you can act on, and the reasoning behind each one. Each note takes a single question, tests every explanation we can think of against the record, and reports which ones survive, including when the answer is that none do.
What we found about shoebox units in Singapore
Shoebox units lost their price premium and kept their rent premium. What that means depends on whether you are buying, selling, renting or renting out.

A new 3 bedroom outside central rents for more per square foot than a 26-year-old one in prime, and that first became true in 2020
In 2025 a three-bedroom in a building under five years old rented for S$4.92 per square foot outside central, against S$4.02 for one over 26 years old in the core central region. In 2019 the comparison ran the other way. The age premium roughly doubled over nine years, from 1.25 times to 1.65, and in 2020 it grew large enough to overtake the thing everyone assumes decides rent.

95% of three-bedroom owners who sold since 2020 made money, and the median gain was $450,000
Of 27,663 three-bedroom condominiums bought and resold, 95.4% sold for more than the owner paid. The median gain was $450,000, or 33.7%, over a median hold of 9.6 years. That works out at 3.5% a year. The losses are concentrated: in the core central region one owner in ten sold below what they paid, and the median loss there was $320,000.
